Abstract: The recently discovered Virgo stellar over-density, which expands perpendicularly to the Galactic disk plane (7< Z < 15 kpc, R∼ 7 kpc), is the largest clump of tidal debris ever detected in the outer halo and is likely related with the accretion of a nearby dwarf galaxy by the Milky Way. We carry out N-body simulations of the Sagittarius stream to show that this giant stellar over-density is a confirmation of theoretical model predictions for the leading tail of the Sagittarius stream to cross the Milky Way plane in the Solar neighborhood.
